PANDAS

From the time he was born until the age of three, Isak McCune of Goffstown was a healthy, smart, sweet little boy.

And then his mother says her little boy just changed. He started having tantrums. Really big ones.

"We called it being held hostage," says Robin McCune. "He would go on and on for hours. We couldn’t leave the house. And then when they finally got to the point where he was just exhausted, then he would come to me and be held. Most of them were four to six hours. They were long."
